Orthogonalization has not been widely used in power system state estimation due to misgivings about its speed. Sparsity related issues and the various advances made in speeding up the orthogonalization are presented. The efficiency of the method is illustrated by tests on various networks. These tests indicate that the performance is comparable to that of the normal equations method
